PLAITING APPARATUS.

' SPECIFICATION forming part of Letters Patent No. 651,181, dated June5, 1900. Application filed December 11, 1899. Serial No. 739,960- (Nomodel.)

To all whom it may concern.-

Beitknown that I, THOMAS F. BYRNE, a citizen of the United States, and aresident of Phoenixville, Chester county, Pennsylvania, have inventedcertain Improvements in Machines for Inserting Tape into Lace Edgings,of which the following is a specification.

The object of my invention is to impart a certain amount of slack orfullness to a piece of tape threaded into a strip or band of lacework,such as that employed as edging for undergarments and the like, wherebya given length of such edging will contain a length of tapein excess ofthe length of the edging, thereby providing projecting ends for forminga knot or bow.

In the accompanying drawings, Figure 1 is a View of a strip of laceedging with tape as inserted therein previous to my invention.

Fig. 2 is a view of a similar strip of edging with tape inserted thereinby mechanism constituting my invention. Fig. 3 is a top or plan view ofmechanism embodying my invention. Fig. 4 is a side view of one of theelements of said mechanism. Fig. 5 is a sectional view of the otherelement of the same, and Fig. 6 is a front view of the same.

Lace edging of the character to which my invention relates consists ofopposite side portions or a, connected by transverse bars or rows ofstitches b, and a tape cl is threaded into such edging by passing italternately under and over these transverse bars.

In machines which have heretofore been devised for introducing the tapeinto the edging no provision was made for introducing the tape inexcess-thatis to say, a greater length of tape than the length of edgingcontaining the same; but such excess of tape is necessary in order thatwhen a length of edging has been cut off to serve as a trimming for theneck or armhole of a garment the tape can be drawn out beyond the endsof the edging, so as to be tied in a knot or bow. In carrying out myinvention I take the edging, with the tape inserted therein, and feed itbetween rollers in such manner that the tape will be drawn forwardfaster than the edging, thus providing an excess of tape proportionateto the difference in the rate of feed. This may be done by passing theedging between -rollers having the portion which acts upon acts upon theedging, although I prefer to use in connection with feed mechanismacting upon the tape a device for frictionallyretarding the sideportions of the edging, while the central portion with the inserted tapeis free from such frictional retardation.

In the drawings, 1 represents a roll having a shaft 2, which is mountedin a fixed bearing 3, and 4 represents a roll disposed directly abovethe roll 1 and having a shaft 5, which is mounted in a bearing 6,having'rods 7 passing down through the lower bearing 3 and provided withheads 8, between which and shoulders on said lower bearing areinterposed springs 9, a lever 10, mounted at one side of the lowerbearing 3, acting upon a pin or stud 11 011 the upper bearing 6, so thatthe latter can be raised and lowered as desired. The roll 4 has araised. central ring or band 12, which normally runsin contact with thelower roll 1, but can be removed from contact therewith by lifting theupper bearing 6. The shaft 5 of the upper roll 4 has a pulley 13 forreceiving a suitable driving-belt, and said shaft also has a spur-pinion14, which meshes with a spur-wheel 15 of somewhat larger diameter on theshaft of the lower roll, so that the central ring or band 12 of theupper roll 4: travels at a somewhat-higher surface speed than the lowerroll 1.

In front of the structure which I have just described and at anysuitable distance therefrom is another pair of rolls 16 and 17, thelower roll 16 being carried by a shaft which is adapted to fixedbearings in standardslS, while the shaft of the upper roll is adapted toboxes which are acted upon by springs, the

tension of which can be adjusted by means of screws 19, so as to causethe upper roll 17 to bear upon the lower roll 16 with any desired degreeof pressure. The rolls 16 and 17 are centrally grooved for the receptionof a tube 20, which extends some distance from the rolls 16 and 17 inthe direction of the rolls 1 and 4. This tube has the lace edging strungupon it-that is to say, it is threaded through the edging so that thecentral cross-bars of the latter are disposed alternately above andbelow the tube, while the tape which is to be applied to the edgingpasses through the tube. The tape is therefore not subjected to thepressure of the rolls 16 and 17; but the edging is confined between saidrolls, and its movement is retarded to an extent dependent upon thepressure of said rolls against each other. Upper and lower guide-bars 21and 22, disposed in front of the rolls 16 and 17, serve to flatten outthe side portions of said edging as it approaches the rolls, so thatsaid side portions of the edging are properly fed between the portionsof the rolls which flank the central grooves and are thereby subjectedto the desired retarding influence, the central portions of theguide-bars having flaring cone portions 23 and 24:, and said bars alsohaving beveled portions 25 and 26, so as to aid in the properpresentation of the edging to the rolls. As the tape is continuallysubjected to the forward pullof the central ring or band 12 of the roll4 and is free from any retarding influence other than that exerted uponit by the pressure of the cross-bars b of the edging, said tape is fedforward faster than the edging, which, in addition to being retarded bythe action of the rolls 16 and 17, is not continually acted upon by saidband 12 of the roll 4c, the latter acting only upon the cross-bars ofthe edging and the side portions of said edging passing between the roll1 and the port-ions of the roll 4;, which flank the central band 12 andare less in diameter than the latter. As a consequence the desiredexcess of length of tape is produced, as shown in Fig. 2, so that when apiece of edging of the desired length has been severed from the stripthe tape can be pulled out so as to project from each end of said pieceof edging in order to form portions for being tied into bows or knots.

Having thus described my invention, I claim and desire to secure byLetters Patent.

1. In a machine of the character described, the combination of rolls forfeeding forward a strip of lace edging having a tape inserted therein,and provision for frictionally retarding the movement of the edgingwithout like retardation of movement of the tape, substantially asspecified.

2. In a machine of the character described, the combination of a pair ofrolls adapted to feed a strip of edging, one of said rolls hav' ing araised ring or band for acting upon a tape inserted in said edging, andmeans for driving said roll at a higher rate of surface speed than theroll with which it cooperates, substantially as specified.

3. In a machine of the character described, the combination of a pair ofdraft-rolls, with a pair of frictional retarding-rollers grooved for thereception of a guide-tube for the edging and for the tape to be insertedtherein, substantially as specified.

4. In a machine of the character described, the combination of thefrictional retardingrolls,the guide-tube adapted to grooves in saidrolls, and guide bars in front of said rolls, substantially asspecified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
